John Gill Commentary Genesis 1:12

"And the earth brought forth grass, herbs yielding seed after their kind, and trees bearing fruit, wherein is the seed thereof, after their kind: and God saw that it was good." — Genesis 1:12 (ASV)

And the earth brought forth grass In great abundance at once; the hills and vales were clothed with it, and so a rich provision was made the beasts and cattle of the earth two or three days before they were created.

[and] herb yielding seed after its kind, and the tree yielding fruit, whose seed was in itself after its kind : wholesome and healthful herbs and plants, and delicious fruit to be meat and food for man, ready prepared for him when created; see (Genesis 1:29–30).

On this day, though after related, were made the garden of Eden, and all the trees in it, pleasant for sight, and good for food; and particularly the tree of life, and the tree of knowledge of good and evil.

and God saw that it [was] good ; which he had now caused to spring forth, grass, herbs, and fruit trees, which were good for men and beast, and this he foresaw would be so; (See Gill on Genesis 1:4).
